For your own classes/types, you could override __new__ to maintain a class-wide (or even wider) weakref.WeakValueDictionary with id as the key and the instance as the (weakly held) value. For the general case, this wouldn't work -- however as your "search technique" checks globals only, it's pretty weak (it wouldn't find a value that's only held as an item in a list even if that list were global, for example). You might do a bit better by checking through gc.get_objects(), but that won't get objects of many types, such as int, float, str... Alex -- http://mail.python.org/mailman/listinfo/python-list
